And with their heads full of knowledge from great philosophers, mathematicians, scientists and writers, who better for great young scholars to learn one last thing from before leaving campus than ... celebrities?

Seriously. Last weekend, Oprah Winfrey, Arnold Schwarzenegger, Pharrell Williams, President Donald Trump, Sheryl Sandberg, Will Ferrell and Octavia Spencer could all be found on college campuses offering some advice to the class of 2017.

Despite being famous for lines so highly intellectual as, “I’m in a glass case of emotion,” and “I’ll be back,” the group actually had some wise words to share. Here’s what the seven of them had to say.

Pharrell Williams, New York University

“To the graduates, you might think your time in education is done, but after you leave here today, I am asking you to let your actions out there in the world... fuel the demand for better education. Engage and inspire — whether on an individual level or loudly within your communities. Talk about your accomplishments. Be humble, but not too humble. Don't be invisible.”

“The days of being an anonymous activist or participant are over. How can we inspire if we are only behind the scenes? How will an anonymous donation ever inspire another? That was the way of previous generations. Don't be like them.”

Arnold Schwarzenegger, University of Houston

“None of us can make it alone. None of us. Not even the guy that is talking to you right now, that was the greatest bodybuilder of all times. Not even me, that has been the Terminator and went back in time to save the human race. Not even me that fought and killed predators with his bare hands.”

“As soon as you understand that you are here because of a lot of help, then you also understand that now is time to help others. That's what this is all about. You got to help others. Don't just think about yourself. Help others.”

“Make sure that it is not about me. That it is about 'we.' Turn the 'me' into 'we,' and I guarantee you that you can change the world.”

Sheryl Sandberg, Virginia Tech University

“As you leave this beautiful campus and set out into the world, build resilience in yourselves. When tragedy or disappointment strike, know that deep inside you, you have the ability to get through anything. I promise you do. As the saying goes, we are more vulnerable than we ever thought, but we are stronger than we ever imagined.”

“You will have good days and you will have hard days. Go through all of them together. Seek shared experiences with all kinds of people. Write shared narratives that create the world you want to live in. Build shared hope in the communities you join and the communities you form. And above all, find gratitude for the gift of life itself and the opportunities it provides for meaning, for joy, and for love.”

“No matter how cliché it may sound you will never truly be successful until you learn to give beyond yourself. Empathy and kindness are the true signs of emotional intelligence.”

“To those of you graduates sitting out there who have a pretty good idea of what you’d like to do with your life, congratulations. For many of you who maybe don’t have it all figured out, it’s okay. That’s the same chair that I sat in. Enjoy the process of your search without succumbing to the pressure of the result. Trust your gut, keep throwing darts at the dartboard. Don’t listen to the critics and you will figure it out.”

“You’re nothing if you’re not the truth. I’ve made a living, I’ve made a life, I’ve made a fortune — really it’s fantastic — from being true to myself and, if I could leave you with any message today, that is it. The biggest reward is not financial benefits, though it’s really good. You can get a lot of great shoes, nothing wrong with great shoes. But those of you who have a lot of shoes know that having great shoes and a closet full of shoes or cars or houses or square footage doesn’t fill up your life. It doesn’t. But living a live of substance can. Substance through your service. Your offering of your whole self. And the baseline for ‘How do you live a life of substance?’ is whatever is the truth for you. What do you stand for?”

“If I give you one message to hold in your hearts today, it's this. Never, ever give up. ... Never stop fighting for what you believe in and for the people who care about you.”

“Carry yourself with dignity and pride.”

“Treat the word 'impossible' as nothing more than motivation.”

“Always have the courage to be yourself.”

“Most importantly, you have to do what you love.”

Octavia Spencer, Kent State University

“It’s my deepest hope that the curiosity that has guided you here continues to be a guiding light in your life. Represent your own curiosities to the world. Point the way forward for future graduates. Keep moving people, keep reading, keep nourishing what makes your voice unique and defend it for yourself and for others.”
